MAXQ305

Low-Voltage Microcontroller with Infrared Module

General Description

Features

The MAXQ305 is a reduced supply voltage, low-power,

16-bit MAXQ microcontroller designed for low-power

S High-Performance, Low-Power 16-Bit RISC Core

S 0.9V to 3.6V Operating Voltage Range

applications including universal remote controls,

consumer electronics, and white goods. The MAXQ305

combines a powerful 16-bit RISC microcontroller and

integrated peripherals including two USART ports and

a SPI master/slave communications port, along with an

IR module with carrier frequency generation and flexible

port I/O capable of multiplexed keypad control. The

MAXQ305 includes 80KB of flash program memory and

2KB of data SRAM.

S DC to 12MHz for Code Execution in Performance Mode

S 16-Bit Instruction Word, 16-Bit Data Bus

S 16 x 16-Bit General-Purpose Working Registers

S Secure MMU for Application Partitioning and IP

Protection

S Memory Features

ꢀ80KB Program Flash Memory

ꢀ2KB Data SRAM

The MAXQ305 can run from a low supply input voltage

of 0.9V, allowing the microcontroller to be powered by a

single alkaline AA battery. Code execution can run at up

to a 12MHz rate, or the execution speed may optionally

be decreased to 4MHz (Green Mode) to reduce power

consumption. In this mode, the IR timer and modulator

continue to run at 12MHz for maximum compatibility with

existing IR application code.

S Additional Peripherals

ꢀPower-Fail Warning

ꢀPower-On Reset/Brownout Reset

ꢀAutomatic IR Carrier Frequency Generation and

Modulation

ꢀOne IR Diode Direct Drive Pin

ꢀTwo High Current Visual LED Direct Drive Pins

ꢀTwo 16-Bit, Programmable Timers/Counters

ꢀOne SPI Port and Two USART Ports

ꢀProgrammable Watchdog Timer

ꢀ8kHz Nanopower Ring Oscillator Wake-Up Timer

ꢀUp to 32 General-Purpose I/Os

For the ultimate in low-power battery-operated

performance, the MAXQ305 includes an ultra-low-power

stop mode (0.4FA, typ). In this mode, the minimum

amount of circuitry is powered. Wake-up sources include

external interrupts, the power-fail interrupt, and the wake-

up timer interrupt.

S Low Power Consumption

ꢀ0.4µA (typ), 2.0µA (max) in Stop Mode, T = +25°C

ꢀ1.36mA (typ) in Green Mode (Code Execution at 4MHz)
